Session won't restore after closing the browser. Back and forward buttons, and menu bar keep getting disabled. Can't use any personalization in tabs behaviour, as the browser apparently doesn't acknowledge what I select in option (nor the ones from FireFox or the ones from TabMix Plus). Directions bar shows not the url where I am, but the last one I open. These problems make the browser complete unusable for my needs, as the one reason I keep faithful to it since the beginning was the ability to adapt it to what I need.
